Comment # 1 on bug 50565 from Michael Kruse
Thanks for the report.

The error means you have an LLVM library (in this case: LLVMPolly) linked more
than once into the address space. For instance, once statically linked into
opt, and once more using `-load LLVMPolly.so`.

The solution is to not add `-load LLVMPolly.so` to the command line: It is
already statically linked in your `opt` executable (due to using the build
option `LLVM_POLLY_LINK_INTO_TOOLS=ON` when building LLVM).
